General

AVR Current & voltage protection relay is designed to protect devices with sensitive operating voltage & currentvalues from errorsthat may arise from mains voltage and Overload.

Device Usage and Principle of Operation

Make the connections of the device according to the connection type. Otherwise, the device may be damaged. Adjust the over-current andhigh & low voltage and settings of the device according to the coperating current and voltage values of the load you will use.

Over-current Error state: If the current value is under the current set values (when the device is not in error), the current value risesabove the current set value, the device waits for the set error waiting time, then the device de-energizes the relay , the error led lurn on, the overload value displayed on the current display flashes throughout the error period.

Voltage Error state: If the mains (input) voltage value is between the high and Low voltage set values (when the device is not in error), the mains (input) voltage value rises above the high voltage set value or under below the low voltage set value; the devicewaits for the set error waiting time, then the device de-energizes the relay, the error led lurn on, the mains linputl voltage value displayed on the voltage display flashes throughout the error period.

Exit the Over-current Error state: After eliminating the load over-current fault, Press twice the on/off key to manual reset or cut off the power supply.
Note_1: Manual reset is to avoid secondary damage to the system by automatically resetting the system without excluding over-current or short circuit.

Exit voltage error state: When the mains (input) voltage value returns to normal / when the reaches a value between thehigh and Low voltage set values the device waits for the set reset waiting time, then the device energizes the relay. the error led turns off, the out led turns on.

Display and Buttons

1 - SET Button:This button is used to save after setting/changing Over-current values & high/low voltage setting values and error wait time.

2 - UP Button: Increase the required value.

3 - Down Button: Reduce the required value.

4 - Manual On/Off Button: For close the device output.In thisstate, the screen will display "off" and the device cannot be automatic reset. Press this button again to Switch on the device intouse again (No failure premise).

5 - Current Display
1St Display Group: During normal operation, the input (mains) voltage value is displayed here,the screen lights up steadily when not in errorstate,the display flashes in case of error (high or low voltage).During the programming process, the value of the relevant program is shownon the display (Over-current and high/low voltage, error wait,reset wait setting values].

6 - Voltage Display
2St Display Group: During normal operation, current value is displayed here, the screen lights up steadily when not in error state,the display fashes in case of error (over-current). During the programming process, the numeric value of the relevant program is displayed here.

7 - LEDs:
A>:Light up when an over-current fault occurs.
V>:Light up when an high voltage fault occurs.
V<: Light up when an low voltage fault occurs.
0ut: Lights up when the device starts to output.

Connection Diagram

The neutral an phase connetcion comes from the mainsmust be connected to the "N"and "L" terminalsat the "lnput" of the device. Neutral and Phase connectionof thedevices that are desired to be protected fromover andunder voltage should be taken from the "N" and“L”terminals in the "Output" part of the device.
